Special organic fertilizer for breeding seedlings of precious timber species

Abstract

The invention relates to a special organic fertilizer for breeding seedlings of precious timber species. The mixing mass ratio of the organic fertilizer to a compound fertilizer is 0.5%, decomposed bagasse and decomposed sheep manure are respectively ground and bunched after dried in the sun, and then the ground bagasse and sheep manure are uniformly mixed according to a volume ratio of 1:1, an inorganic compound fertilizer with the ratio of N to P to K being 15%:15%:15% is added, and then a special matrix fertilizer is prepared. The novel fertilizer and a formula of the fertilizer belong to an independent innovation product which is a slow-release organic and inorganic compound fertilizer, and the fertilizer has low cost, multiple functions and good effects, and can scientifically regulate the vegetative growth and reproductive growth of the seedlings, improve physical and chemical properties of soil, perfect the soil structure, form micro-aggregates, and have strong cation exchange force and excellent air permeability, water holding capacity and water permeability. The organic fertilizer disclosed by the invention is complete in nutrition and capable of improving soil properties, and has easily adjusted nutrient ratios, high nutrient supply rate, high mineralization degree and long fertilizer supply performance and time.

Description

technical field [0001] The invention relates to a special organic fertilizer for raising seedlings of precious timber species, which belongs to the technical field of fertilizers. Background technique [0002] Foreign advanced forestry developed countries such as the United States, Finland, France and Germany have taken the lead in using special fertilizers, light substrates and self-controlled greenhouses in the process of forest tree seedlings. In recent years, France has taken the lead in developing Fertiss non-woven fabric container seedlings, and light substrates to fill containers. The main nutrients in the light substrates are organic and inorganic fertilizers, which have achieved good results in seedling cultivation. my country's forest tree seedlings have also gone through the process from traditional bare-root seedlings to container seedlings, and the application of fertilizers has changed from ordinary fertilizers to special fertilizers. Due to the lack of specia...

AI Technical Summary

Problems solved by technology

Conventional container seedlings have a large capacity, the substrate is too tight, and the air permeability and water permeability are poor, which is not conducive to the growth and development of the root system.
